Pay more than the minimum - even $25 extra makes a big difference over time.
Consider a balance transfer to a 0% APR card (watch for transfer fees).
Call and ask for a lower APR - many issuers will negotiate, especially if you have good history.
Use windfalls (tax refunds, bonuses) to make extra payments toward principal.

Credit card interest is calculated using your Average Daily Balance multiplied by the Daily Periodic Rate (APR ÷ 365). Interest compounds daily, meaning you pay interest on interest. A $5,000 balance at 20% APR costs about $83/month in interest if unpaid.
As of 2024, average credit card APRs range from 20-25%. Excellent credit may qualify for 15-19%, while store cards often charge 25-30%. A "good" APR is below 18%. However, the best strategy is paying in full monthly to avoid interest entirely.
Always pay more than the minimum when possible. Minimum payments are designed to maximize interest paid to the card company. A $5,000 balance with minimum payments could take 15+ years to pay off and cost more in interest than the original debt.
Snowball: Pay minimums on all cards, put extra money toward the smallest balance. Good for motivation. Avalanche: Pay minimums on all, put extra toward the highest APR. Saves more money mathematically. Choose based on what keeps you motivated.
Balance transfers move debt from a high-APR card to one with a 0% intro APR (typically 12-21 months). Watch for transfer fees (usually 3-5%). You must pay off the balance before the intro period ends, or remaining balance gets hit with the regular APR.
Yes, closing cards can hurt credit by reducing available credit (increasing utilization ratio) and shortening average account age. Consider keeping old cards open with occasional small purchases. Only close if annual fees aren't worth it.
Credit cards are revolving credit — monthly interest on your balance is charged at your APR / 12 on the average daily balance. Paying only the minimum can extend payoff to decades; the calculator shows what happens with fixed-payment vs minimum-only vs extra.
